4.3 USB Hub Selection
4.3.1 USB Hub Switch by Push Button
You must enable Hub Auto-Switch function before you can use push
button to switch USB Hub. There are two ways to toggle Hub Auto-Switch
alternatively:
Press any push button on KVM front panel for 3 seconds.
By using hot key: [Scroll Lock] + [Scroll Lock] + [H]
After Hub Auto-Switch function is enabled, the Hub auto-switch /
Auto-Scan Indicator on front panel will turn ON statically, and USB hub
can be switched along with selection of host port by push button on front
panel. The USB hub switching time is one second later after port switch,
the reason to delay the USB hub switch is to decrease USB enumeration
loading if user changes active port very fast.
4.3.2 Hot Key Switch for USB Hub Selection
If Hub Auto-Switch function is disabled, the USB hub switch is
independent from host port. You can use the following hot keys to switch
USB hub to specific port:
2-Port USB DVI KVM
[Scroll Lock] + [Scroll Lock] + [Q]: Switch USB hub to port 1
[Scroll Lock] + [Scroll Lock] + [W]: Switch USB hub to port 2
4-Port USB DVI KVM
